1.7 Password Protection and Callback
The modems provide password protection with four operation modes
that may be combined freely (with/without callback and released callback/
forced callback). Max. 20 callback numbers are protected individually
with a password. Any alterations are protected using a super password.
A register counts wrong passwords thus providing a hacker protection.
1.8 Remote Configuration
The modems are designed for remote configuration. A connection can
be setup e.g from a remote station to the modem. The remote configuration
can be initiated just by typing a special password.
1.9 2/4 Wire Leased Line Operation with Dial Backup
This feature is only available for the standalone and rackmounted
versions!
A special board for 2/4 wire leased line operation with dial backup feature
is available as an option. Max. 20 backup numbers may be stored. During
failures on the leased line the modem calls the stored backup numbers
until it is able to initiate a switched line connection. In the meantime the
modem
checks the leased line constantly and reswitches automatically if the
leased line is operational again.
1.10 Fax Operation
The fax option of the modems allows for sending and receiving faxes
with a special fax software that should be installed on your computer
(e.g.: RVS-Com for Windows, WinFax Pro 3.0). The fax option is
compatible to:
• ITU-T (CCITT) group 3 (Rec. G3)
• TIA/EIA CLASS 2
1.11 License
The modems are licensed for operation in public and private networks by
the national german licensing authorities.
